PUMP;`

` SPECIFICATION forming part of Letters Patent No. 282,973, dated August 14, 1883.

Application filed November 1,1881. (Model.)

Beit known that I, J oHN EVERITT, a citi-` zen of the United States, residing at Prairie City, in the county of McDonough and State of Illinois, have invented certain new and useful Improvements in Pumps7 of which thefollowing is a specification, reference being had therein to the accompanying` drawings.

This invention relates to double acting pumps; and it consists in constructions and` combinations, hereinafter described, and set forth in the claims hereto annexed.

In the accompanying drawings, which illustrate my invention, and in which the symbols or reference letters used indicate the same tional elevation. Fig. 2 is a bottom plan, seen from below. Fig. 3 is abottom plan, seen from below, of one of the fixed cylinders.

Fig. 4 is a section through one set of cylinders 'and rods f.

Referring to the drawings by letters, letter Arepresents the pump-stock on Vwhich the .working parts are mounted, and extends from above the pump-handle to the bottom of the well. .The stock A is tubular from its top down to a point where it branches into two pipes or tubes, a c. Each tube a has an en-` larged end or cylinder, B, with a valve, b, in its lower end, which is seated on the perforatediiottom b of the cylinder. (See Fig. 3.)

C C are sliding cylinders, with their upper ends open, so they can be placed one over each cylinder B, and slide lengthwise thereon.

The bottom of each cylinder C is formed of two parts, a valve-seat, cl, and a strainer, c, each having perforated lipslwhich register with perforated lips on the lower periphery of'cylinderC, and through all of which the rods f pass and are secured, as shown in Fig.

with, and the same means that are used for holding the bottom and the cylinder together `are utilized in supporting said cylinder from tends but a short distance below the bottoms ofthe cylinders C when they complete their downward strokes, respectively.

D is an ordinary spout.

E is the handle, hinged or pvoted to the pump-stock at its mid-length portion. From each end` ofthe handle E a rod, F, extends downward, and is provided at its lower end witha cross-head, j', from each end of which a rod, f, extends downward, one on each side of a cylinder, C, and are connected thereto by` passing through lugsl on the cylinder and part c and c2, and through nuts cq placed on the bottom of the lugs on strainer c, as shown in Fig. 2.

In operati/on the handle E is operated in the ordinary manner, sliding the cylinders C al-` ternately.V It is not deemed necessary to describe the precise manner in which the water` is received in the cylinders C and forced upward through the cylinders B and stock A to the discharge, as any one skilled in the art will readily see the operation from an inspection of Fig. l.

By means of my construction, and placing the'cylinders C so that at the ends oftheir* downward strokes' they will come very near the bottom of the well, I am enabled to draw through the lips onsaid cylinder and bottom,

and secured thereto, substantially as described.

2. In a pump, the combination of a cylin- The parts of my pump being all` der having perforated lips on its lower periphery,V a bottom having a valve-seat, a strainer, and perforated lips, and rods'which `secure the bottom and cylinder together, and

adapted to lift Asaid cylinder, for the purpose In testimony whereof I affix my signature in presence of `two witnesses. e
